“…Whereas in typical grid‐connected motor drives an EMI limit applies at the AC input terminals, there are also multi‐drive applications where the individual inverters operate from a distributed DC bus. Then, in certain applications, the EMI limits must be fulfilled at the inverter's DC input terminals but not at its AC output terminals; hence, a DC‐side placement of CM filters is needed [23]. However, as initially proposed in [17, p. 36] and shown in Figure 1b, the CM inductor can be moved to the DC side also for grid‐connected converters (for which the EMI limits apply on the AC side) without changing the system's behavior with respect to the DC and AC terminals.…”

This letter presents a hardware demonstrator of an all-SiC three-level T-type (3LTT) inverter with the common-mode (CM) EMI filter stages placed on the DC input instead of the AC output side, targeting, for example, high-efficiency PV applications. The extensive experimental characterization shows that state-of-the-art SiC transistors and a DCside CM filter enable an unprecedented peak/full-load efficiency of 99.4% (calorimetric measurement) at 12.5 kW and a power density of 2.4 kW/dm 3 (39 W/in 3 ). The demonstrator fulfills CISPR 11 Class A EMI regulations as well as upcoming EMI standards for the frequency range of 9-150 kHz. Compared to other high-efficiency converters, which often employ bridge legs with more output voltage levels, the described 3LTT concept thus offers a very favorable trade-off between complexity and performance.
